Death investigation leads to drug charges, Spencer man's arrest

The Clay County Sheriff's Office on Friday said it is still looking into the circumstances of a South Dakota woman's death at nightfall Thursday night.

Deputies were called at 9:53 p.m. Thursday to 3140 100th Ave. for a medical call reported as an unresponsive female. They found 30-year-old Casey Blaine Eleeson, of Huron, South Dakota, deceased in a camper on the property.

First responders joined deputies at the location, which is just north of the M22 and U.S. Highway 18 intersection in western Clay County.

Authorities say they found 43-year-old Robert Ryker, of Spencer, in possession of what is believed to be methamphetamine and marijuana. He was arrested at 1:21 a.m. Friday on two counts of possession of a controlled substance.

"We’re not saying he was involved with the death," Chief Deputy Zach Larsen said. "She was merely living with him over the last couple of days at his camper."

Larsen said authorities are still trying to determine what kind of relationship Ryker and Eleeson had.

Eleeson drew headlines in late 2009 when she was the center of a multistate investigation. She was accused of stabbing her father with a kitchen knife in Rapid City, South Dakota, where she lived at the time. Eleeson was charged with a second count of attempted first-degree murder when she then drove across the city and shot her mother on Dec. 29, 2009. She eluded authorities until Jan. 20, 2010.

She was arrested without incident when authorities found her at a remote cabin in the Lake George area of Colorado. Eleeson underwent a mental health evaluation and was diagnosed with paranoid schizophrenia and bipolar disorder, according to reports from South Dakota. She received treatment and was granted a conditional release in 2013.

Larsen wasn't ready to draw a connection between Eleeson's past and the medical call Thursday night.

"As far as her family history, we haven't gotten that far yet," Larsen said. "This is an ongoing investigation here today. We're looking into a little bit about her and Mr. Ryker ― and her body's been sent to the lab for an autopsy. At this point, we can't even speculate as to why she's deceased."

  • #1- Not his camper as he has been living in a residence elsewhere. Milford. (FACT).

    #2- This girl probably overdosed.& the "relationship" is probably just a drug and sex relationship bc HE has been in a relationship with someone else and doing all this behind her back. He is a liar. a manipulator and a sociopath (my opinion)

    #3- This guy needs help and kept off the streets too. Keep him locked up!
